Myinvention relates to ya 4nozzle :device particularly adapted for I-oil "burners, and more particularly to 'means for cleansing the duid passages of such nozzle device Whilelthe device -is-in situ.

Uil burner-s usuali atomizer `to 'assist'l in- 'the conversion of l`the ,petroleum oils l'into gaseous hydrocarbons.

ers, y'it is'to be :understood-that the invention is lof broaderwapplication and may be embodied lin 4other tor-ms ofy nozzles whereV it is desired tofpr-ovide'fto'r 'the cleansing of the y f v Apassageofthe nozzle without disassembling. y ineludejsomeiform .of

`thebody vmember of the device --having an Y opening 11 for the supply-of fuel. A vnozzle "head or'blind nozzle 12`may loe-'screwed onto ,one end' leil-the body member 10. ithin the In vsaidillustrativej drawings, 10 indicates body of the-device is there; regulating 4or nozzle :member 13, Vthe 'frontend 110i which may be'formed'to `lit int-o the passage 15 in ,the blind vnozzle `member '12. The regulating member 13 lhasa longitudinal slot-16.' Wien the regulating member 131s seated linthe passage in the nozzle'-member 12, the bottom and vsidewalls 'of the slot v16 in the regulati-ng member together with a part of the circumferential y wall of the passage 15 Yin the nozzle Amember form an-oriice 17 for the emission ofluid. Fluid comes in through the opening 11, passes through the body member I Y 110', and thence out through theY orifice 17. The regulating member '13, asl will be deis seated `in the passage 15 vof the-blind nozzle 12 whenlin operating-position.' A fixed cleanou-tmembe'r such as the knife 18 is arranged in the slot 16' 'of the regulating member '13 Vso thatwhen the regulating member 13 is moved back from its normal Vposition the v tknif-e'l will vvcleanse the .slot '16 of carbon or sediment. v I Y `In the particular 'ormillustrated, the regulating vmember 13 is guidedin a guide mein-- 'ber 1'9which is zin fixed relation to the body memberlO.` This guide 'membermay have a flange 20 which'is .firmly held between the Aboily"member :10 and the nut or closuremember 21.- The imi-m18 ispreferably ,'Xedto the guide-member' l^9las by means I'of' pins 24:(

The regulating member 13 is hel-d against ro- AYtation in the' guide member'19 preferably by vmeans ot the knife 18 which :engages in the islot16'ofthe.regulatingmember. Y

Iii)

The regulating member 13 may be retracted by an actuating member 22. As specifically shown, the regulating member 13 is connected by means of screw threads 23 to the threaded portion of the actuating member 22. The actuating member may be journaled in the guide member 19 as shown, and

if desired may be held against longitudinal movement between a shoulder on the guide member 19 and the nut 21. If desired, the actuating member 22 may have a rearward pro-V device to the orifice 17. When'the slot 16 in the regulating member 13 is in need ofcleansing, the actuated member 22 is rotated. The screw threads of theV actuating member 22k engage in the screw threads of the regulating vmember 13, and since the regulating member is prevented from rotating by reason of the engagement of the knife 13 in the slot 16 of the regulating member, the screw effect of the threaded portion of the actuating member 22 upon the threaded surface of the regulating member 13 serves to retract the regulating member 13 so that the knife 18 passes through the slot 16, thus clearing the slot of any carbon or clogging Amaterial.

lVhen the regulating member 13 is retracted,

any clogging material which has collected upon the walls of the passage 15 will be blown out.V After cleansing, the actuating member 22 is revolved in the opposite direction and the screw effect of the threaded portion of the actuating member engaging in the threads of the regulating member 13 will return the regulating member 13 to its seat in the nozzle member 12.

It will be seen that I have provided a vvery simple and effective cleansing means which Y is of sturdy construction and not likely to get out of order. By retracting the regulating member 13 not only is the fluid passage 16 properly cleaned by the clean-outvmember 18, but carbon y or other clogging material which may collect in the passage 15 and on the front end of the regulating member and which would not beremoved by the clean-out member will be blown out by the passage of fluid rushing past the outside of the regulating member at the beginning of retraction. All of the parts are of simple form and readily manufactured and. all parts are easily ascessible for renewals or repairs. Y y

While the invention has been described in considerable detail and one specific form shown in the drawings, it is to be understood that the invention may be otherwise embodied and employed in connection with injectors, nozzles, and the like, of various types other than that herein shown.
